Negative numbers help us to model many real world situations.
Essential Question:
How do I put positive and negative numbers in order?
1.3A) Arrange the following temperatures in order from lowest to highest: -8degreesF, 4degreesF, 12degreesF, -2degreesF, 0degreesF, -15degreesF
-15degreesF, -8degreesF, -2degreesF, 0degreesF, 4degreesF, 12degreesF,
B) The temperature reading on a thermometer is 5degreesF. Tell what the new reading will be if the temperature:
1) Rises 10degreesF: 15degreesF 2) Falls 2degreesF: 3degreesF 3) Falls 10degreesF: -5degreesF 4) Rises 7degreesF: 2degreesF
C)The temperature reading on the thermometer is -5degreesF. Tell what the new reading will be if the temperature:
1) Falls 3degreesF: -8degreesF 2) Rises 3degreesF: -2degreesF 3) Falls 10degreesF: -15degreesF 4) Rises 10degreesF: 5degreesF
D) In 1-6, give the temperature half way between the two given temperatures:
1) 0 and 10degreesF: 5degreesF 2)(-5) and 15degreesF: 5degreesF 3) 5 and (-15)degreesF: -5degreesF 4) 0 and (-20)degreesF: -10degreesF 5) (-8) and 8degreesF: 0degreesF 6) (-6) and (-16): 5degreesF
E) In 1-4, tell which temperature reading is farther from -2degreesF.
1) -6 or 6degreesF: 6degreesF 2) -7 or 3degreesF: They are equal 3) 2 or -5degreesF: 2degreesF 4) -10 or 5degreesF: -10degreesF
F) Explain how you determined your answer for part 4 of question E.
To get the answer from partProxy-Connection: keep-alive Cache-Control: max-age=0 04 of question E, you need to find out which # is further awayProxy-Connection: keep-alive Cache-Control: max-age=0 0from -2degreesF, because the question is which reading is farther away from -2degreesF. So you subtract 10-(-2) and (-8)-(-2), and whichever one is greater, is the answer. 10-(-2)=12. (-8)-(-2)=6. So 10degreesF is the answer.
1.3F/U 1) Give the opposite of each number:
a)-7:7 b)18:-18 c)-42:42 d)0:0
2) Name two #s on the number line that are the same distance from -2. Are these #s opposites?
5 and -9 are the same distance between -2. No, they are not opposites. If the question was 'are the #s that have the same distances from 0, opposites?' then, yes.
At the end of Mr. Hazan's MathMania game, the scores of the five teams are as follows:
Team A: -50 Team B: 150 Team C: -300 Team D: 0 Team E: 100
3) Order the teams from first place through fifth place:
1)Team B, 2)Team E, 3)Team D, 4)Team A, 5)Team C
4) Draw a # line. Mark and label each team's score. Label the point for each team with both the team letter and the score. 4) Team C(-300) Team A (-50) Team E (100)
Team D (0) Team B (150) 5)What is the distance between Teams A and B?
The difference is 200 pts.
6) What is the distance between Teams C and A?
The difference is 250 pts.
7) What is the distance between Teams D and E?
The difference is 100 pts.
8) Tell how each team, by answering one question, could change their score to 0. Give the point value of the question, and tell whether the team must answer the question correctly or incorrectly. If this is not possible for a particular team, explain why.
Team A: They need to answer a 50pt question right in order for their score to be 0.
Team B: They need to answer a 150pt question wrong in order for their score to be 0.
Team C: They need to answer a 300pt question right right in order for their score to be 0.
Team D: It is not possible for this team to answer a question and be right/wrong and still have their score as 0 because when you add/subtract and number from 0, the answer will never be 0 again.
Team E: They need to answer a 100pt question wrong right in order for their score to be 0.
